Asimov was considered to be one of the “Big Three” science-fiction writers during his lifetime. “A few years ago, the idea of a computer you could put in your pocket was just science fiction.” Background information 3 Asimov is perhaps best known for his Foundation series, the first three books of which won the Hugo Award for “Best All-Time Series” in 1966. His other major works are the Galactic empire series and the Robot series, in which he put forward the Three Laws of Robotics — an idea which continues to exercise some influence today. 4 Complete the table to compare life on Earth with life on the Moon.

The boy has a best friend Robutt, who is a robotic dog. Robutt was programmed to love and keep the child safe so that the boy could wander among the moon craters unhazardously. Learning to learn What is foreshadowing? Foreshadowing is when the author gives a clue as to what is to come later in the story. This often appears at the beginning of a story, or a chapter, and helps the reader develop expectations about the coming events in a story. What life on the Moon is like in the novel? We can see from the passage that when people living on the Moon want to go outside, they normally have to wear spacesuits. We can also see from the passage that people can only communicate by some special devices on the Moon because there is no air but vacuum. Complete the summary of the story.

His parents think it would be good for Jimmy to have a real dog, and that he would like it. They want to send Robutt to another family. To his parents’ surprise, Jimmy refuses to accept the real dog, because he loves Robutt and he believes Robutt loves him too. For Jimmy, Robutt is not just a mechanical dog, but a real friend. They think Robutt is a mechanical imitation of a real dog. He loves Robutt and treats him like a real dog. Give a talk on whether it is possible to have a real friendship with a robot. Answer the questions to help to form your point of view. Why do Jimmy and his parents have different feelings towards Robutt? Because Jimmy was born on the Moon，he has never seen a real dog. He has been getting along well with Robutt，and thus has developed an affection for him. He cannot figure out why a real dog is better than a mechanical dog，despite his father’s explanation. While Jimmy’s parents have seen real dogs before they left Earth. They know what real dogs look like. They think Robutt is just a machine. Answer the questions to help to form your point of view. If you were Jimmy, which one would you choose, Robutt or a real dog? If I were Jimmy, I would choose to own a real dog, because I need real comfort and genuine love and loyalty from my pet. Give a talk on whether it is possible to have a real friendship with a robot. Organise the main points you would like to cover and complete the table. Point of view Arguments Supporting details Conclusion It is possible. We enter the era of social robotics. Like the close relationship between Jimmy and Robutt. We will all be having relationships with robots. 15 Give your talk to the class. Think & Share 1 What are the similarities and differences between Robutt and a real dog? Similarities: Both are able to respond to orders given by human beings. Both can outrace human beings. Both can guide and protect human beings. Differences: They have different appearances. A real dog is a living creature, while Robutt is a machine. A real dog loves human beings as a result of its nature, while Robutt is just adjusted to act as though it loves human beings. Think & Share 2 Is there any foreshadowing of Jimmy‘s final decision? Find clues in the reading passage. Yes, there is. At the beginning of the story, we know Jimmy has never seen a real dog. It also seems that he spends a lot of time with Robutt. Jimmy plays with Robutt enthusiastically, shouting “Come on, Robutt”. In the middle of the passage, we are told that“ Jimmy couldn't go wrong while Robutt was around", indicating that Robutt protects Jimmy well. Notes to the text 1 The outer side of the crater sloped southward and the Earth, which was low in the southern sky, was nearly full, so that the entire crater-slope was brightly lit. Paraphrase: The entire crater-slope faced south and was brightly lit by the sun‘s reflection on the Earth, which was just above the horizon to the south. 本句是一个复合句， 其中 and连接两个并列句， which 引导非限制性定语从句，so that引导结果状语从句。 southward 是副词, 意为“向南方”。以-ward结尾的副词都有“向⋯⋯方向”的意思, 如forward 意为“向前”, northward 意为“向北方”。 so that在此引导结果状语从句,意为“因此, 所以”。 I took no notice of him, so that he flew into a rage.(我没注意到他, 他因此大发雷霆。) Notes to the text 2 The slope was a gentle one and even the weight of the spacesuit couldn't keep Jimmy from racing up it in a floating hop that made the gravity seem nonexistent. Paraphrase: Jimmy was able to bound easily up the gentle slope, hardly noticing the weight of his spacesuit because of the Moon's low gravity. keep sb from doing sth意为“阻止某人做某事”, 相当于 stop sb from doing sth。 These worries kept her from sleeping properly.(这些烦恼使她睡不好觉。) 本句中的racing up, a floating hop等描述非常生动, 教师可以先帮助学生复习 race, float，hop的意思，然后引导学生想象这一系列动作的画面。 Notes to the text 3 Jimmy couldn't go wrong while Robutt was around, tripping him when he was too near a rock, or jumping on him to show how much he loved him, or circ ling around and squeaking low and scared when Jimmy hid behind a rock, when all the time Robutt knew well enough where he was. Paraphrase: Jimmy was always safe while Robutt was with him. Robutt would knock him out of trouble when he was too near a rock, jump on him to show how much he loved him, or go round in circles making noises as if he was scared when Jimmy hid behind a rock. Robutt always knew very well where Jimmy was. trip意为to make someone fall by putting your foot in front of them when they are moving“把(某人)绊倒” He didn't notice me and stretched out his foot suddenly, almost tripping me.(他没注意到我, 突然伸出脚, 差点把我绊倒。) Notes to the text 4 Jimmy held out his arms and Robutt was in them in one bound. Paraphrase: When Jimmy opened his arms, Robutt jumped into them at once. hold out意为“伸出(手或手里的东西)”。 She held out her hand to him.(她向他伸出手。) bound 是一个多义词, 在本句中用作名词, 意为a long or high jump made with a lot of energy“跳跃”。 Notes to the text 5 I love Robutt and that's what counts. Paraphrase: I love Robutt, and that is the most important thing. count是一个多义词, 在本句中用作动词, 意为to be important or valuable“重要”。 What really counts is whether you have good computing skills.(真正重要的是, 你是否拥有良好的计算机水平。) Thanks！ $$
